A Nonlinear Beamforming algorithm for wireless Communication Systems

A nonlinear beamforming algorithm with less computation complexity is presented. Its weight vector can be obtained by incremental method, this will reduce largely computation complexity and easy to be implemented in DSP. Moreover, the high-order characteristic of received signals is utilized, so it outperformances the linear minimal mean square error (MMSE) beamforming method in terms of a reduced bit error rate, and it has superiority over Bayesian beamformer in computation complexity
